Hi Folks, Great site! Does anyone out there have a Quad 303 for parts? I have to replace the 2 amplifier boards, which I fried during re-biasing. Alternately, a COMPREHENSIVE modern transistor-equivalent list for the 303 with any re-biasing values? Cheers, Dougie (in Canada)

I'm looking for an input transformer 600 0hm for one of my 50e's. I can swap it for 2 sets of input connectors and power connectors. Erik

Comments:
Just got the new electrostatics so selling the 63s and Gradients plus crossovers, together or seperately if someone buys the Gradients first. Anyone interested? Excellent condition throughout.

I would like to buy a CD player that fits on an ordinary bookshelf (11") like my Quad components. Leaving aside the Quad CD player, which seems to be quite rare, is there any such machine?

Comments:
To tell the difference between a Mk I and Mk II Quad 606 ( there is a big differnce in internals) the top of the MK II has bevelled edges instead of straight edges. The internals are much bigger ( 3 times the size ) Caps 15,000 in lieu of 6,800 Caps and a large toridial transformer in lieu of a C core, plus the MKII has a wider bandwidth and more grunt.

As I already anticipated on 21th of November I now do use a 66 Pre (MKII) with the good old IIs and the ESL63: it sounds great! Any one else with similar experiences?

Comments:
Anyone had experience of bi-amping using a 306 &606. Any comments on the results, and on connecting the amps? The speakers I have are Castle Harlech.

Comments:
Would like to buy a Quad 44 (with view to connecting to the II's)

I recently purchased the above from a deceased estate (with no leads) there came with it a pair of B&W speakers & a Sony PSx40 Deck. Anyone interested in purchasing these. Tony.

Comments:
I'm 'modernizing' my equipment. Just bought a pair of 3 years old ESL63 (on stands). Next step: find and modify a 66 pre for my still superb 22's (ok, purist amongst us won't like it - but it works and it sounds good - I've heard it). Anyone interested in my AAM tuner and/or FM (acoustical - for collectors)? Wouldn't like to put it on ebay amongst computers, dishwashers etc. The AM is up and running well - the Acoustical FM is being serviced for the time being).

Thanks for the site. I have been using the Quad 405-2 for driving my b&w 805 Matrix for some time now. Unfortunately it doesn't work anymore, but I am in process of fixing it. BTW. a wonderful combination with Alphacore Goertz MI1 biwiring cables and Goertz Interconnects to my Teac VRDS 10 cd player. I am using a QED Vector preamp. (MB47) The 405-2 h s been modified, but my T2 (Triac) has blown. (On one board) Part number : TIC216D The problem is that I cant find it anywhere. Is there a replacement part for this specific item? Any help would be appreciated.

Firstly Quad response to e mails with queries etc is 1st class. I have e mailed them many times over the past few months and always get a response within a day or two. First class honours go to Rob Flain service Manager @ Quad. Secondly, does anyone have a Quad FM4 or 606 in mint condition that they want to sell. I would prefer Australia only due to postage and duty costs and our terrible exhange rate. If so e mail with details and price etc. Here's hoping!!!!!!!!!

Comments:
Have two QUADII amp in bad shape. I like to Crome the amp instead of repaint them in Original color. problem is the Transformers. How to take out the transformer from the covershell and after the Crome prosidure, Refill transformer tar and put the transformer back to the Cromed covershell. How should I do ? /peter/

Comments:
I own a set 33/303 manufactured in 1968. Now they are for sale. 100% playing and still strong. All original. Serial nr 33:5176 and the 303:9919. Make an offer! I am from Holland.

Comments:
using 77 int for bi-amping; does anyone know the internal cicuitry etc of a 77 int, and how it relates to the pre-amp in and out plugs? I have 2 x 77 int's, and wondered about using them to bi-amp; i saw an article about using a 77 int and a 77 power o bi-amp, wanted to do the same thing. is a 77 int basically a 77 power with a pre-amp stage included? if i ran the pre-out from the "main" amp to the pre-in of the "slave" amp would that give me effective bi-amping? what order to connect things in any thoughts? (if it doesn't work , anyone want to buy a 77 int?) thanks kieran

Comments:
Does anybody out there have access to, or a copy of the ORIGINAL design and construction details for the QUAD II output transformers? I'd be willing to pay for them. It occured to me that there are only a finite amount of original Quad II's available thes days & they're now fetching ridiculous prices. Obviously the originals left are not going to last forever. What happens then??? I would really like to keep these classic designs alive and kicking for each generation to enjoy, rather than as a distant mem ry of a once golden age of Hi-Fi. Fortunately, all components necessary to rebuild Quad II's are available, and there are now several companies offering superb quality reproductions of the KT66 valves (in particular the Harma Diamond range, along with Groove Tubes and Golden Dragon). New hassis can even be manufactured by companies such as Radshape (www.radshape.co.uk), allowing for slight modifications for modern type connectors. The only fly in the ointment that stops the user from constructing his/her own Quad II from the original design is the non-availability of a genuine reproduction output transformer (Sowter no longer produce their design due to instability problems, and Wo side's unit is an 'approximation' of the original - not an exact copy). I pestered Quad about these for over a year and was always told they'd be available soon. I then found out that the company who wound these reproductions has gone out of business!!! I these transformers are never to be released again, the Quad II will eventually become a relic of the past. If you feel as strongly about this as I do, and would like to keep the Quad II from becoming obsolete in years to come, please join me in urging Quad to begin re-manufacturing replacement output transformers (and mains and choke for that matter) for these classic designs again. Look forward to hearing any views you may have on this. Cheerio!!!

Comments:
Does anyone have a single Quad II for sale in England? Doesn't have to be working or even have valves, but all transformers MUST be sound. Tatty examples considered, but no heavily dented and/or rusty units. Reasonable prices only please!!!!

QUAD owner since 1979 from Slovenia. I am looking for 405 in good condition (production near 1979).

Comments:
keen to learn more about Quad II/40

Comments:
Would like to swop my 57's (+ RATA stands) for a pair of 63 (pref. black). I am also looking for a 67 or 66 CD-player. I'm located in Munich and regularly looking at this exciting site.

Comments:
Would it be possible to bridge both of my 405s and use each as a monoblock? What would result in terms of power output and sound quality?

Comments:
Hi folks Any one interested in a piece of Quad kit I picked up some months ago? It is a cabinet for the 3 series ensemble - 33/303/fm3 and deck (in this case a Thorens). It does not have a makers mark on it but judging by the quality and materials it may be Quad b ilt. It would be great for anyone keen on retro type decor. It is in fairly good condition and I woulld like to pass it on to someone who will use it with the right amps - I simple use it as a table... any reasonable offer will be accepted (amps/deck not nculded!) Also, does anyone have any comments re my 2 34 control units? One has DIN connects and an Aux input, the other has Phono and a CD input. I have used both with my Philips CD and cant tell any difference - which one might you be tempted to part wiith?

Comments:
re DIN Phono - thought so... I have an unusual (Quad built?) cabinet for the 3 series ensemble plus deck, ideal for retro design fans - any one interested email me for full details

Comments:
Simon, the reason for the change from DIN to Phono was for no other reason than consumer/marketing demand. Same thing applied to Video standards. Beta is superior to VHS but VHS won the battle.

Comments:
For years Quad insisted on using Din type connection, saying they had "superior mechanical and electrical properties" Half through the 4 series, they changed their tune - anyone know why?

Comments:
I'm considering Bi-Amping to my E.S.S AMT3's, using the 405 to drive bass and low mid and the 303's beaut clarity to look after the HEIL drivers. Any thoughts regarding crossover at 33 output stage? Cheers, Mort

Comments:
I just purchased a Quad 405 and the right side was partially crushed (only the plastic front left edge). Anyone know where or how I could fix this? Cheers.

Comments:
Im Selling the pre and power's but keeping the Fm2 as it's a damn fine tuner. My question is how do i increase the output from the tuner to 500mv or higher. If anyone can help please e-mail me.

Comments:
Excellent site as a Quad fan who works in Huntingdon there is more info here than I can get localy, even thoug I know several of the Quad team Well done

Comments:
I have Quad-33 and Quad-405 since 1976, I know these stuff is too old but compared with todays technology especially the complicated electronic development, I can say that Quad has built the finest from tubes to solid state.

Comments:
Anyone interested in my bi-amped system. This kit has been given a thorough cap replacement, also the vol pot is now a Blue Alp's. Those STUPID and now dangerous Bulgin plug's and socket's have been changed to a perminant mains lead. Any taker's, sensible offer's please. Upgraded force's ( wife ) sale

Comments:
The above gear is for sale.It needs a bit of work. It needs an electronic condensor, the switch assembly is intermitent and needs 2kt66 and 3 ef 83 to work perfectly .Apart from mentionned, its in very good shape, everything is original and as never been modified or repainted. Make an offer!

Comments:
If i buy the Ah-tjoeb player, it has a volume contr. on the remote. Does that mean i could connect it straight to the 303 and only use the 33 for the FM3?? It could be a good idea as most people seem to think that the 33 is the weak point in the setup??? mmmmmm! what do i know ?? All the best, Magnus

Comments:
I am looking for a circuit diagram for the 33. it was running well for a while and then I lost some of the range. If anyone can help I will be a happier man.

Comments:
Great site! Anyone got a Quad II for sale (220V version) ? I need one to complete a stereo pair.

Comments:
Hi all! I need some advice.... I am currently using an old Philips cd 692 with my system but it's starting to skip quite badly so i'm in need of a replacement. Has anyone got any sugestions on a cdp that goes well together with the Quad? (i'd like a bit ore omphh in the bass but not loosing the wonderful clarity ) I'm not concerned about having the latest in cdp, but rather pay descent money for something older but GOOD. What about the old quad cdp's?? And finally: should i biamp using a second 303?? I k ow it would LOOK damn good, but would it be worth it soundwise?? THANKS TO ALL

Comments:
What a fantasic site! Certainly the most comprehensive, the most enjoyable & the best looking Quad site around - can't wait for the updates on the new Quad II forty! But... whatever happened to the next installment of the Quad II restoration saga??! Keen o see what happens next as I am currently restoring a pair myself using Kiwame carbon film resistors, Audio Note paper in oil capacitors, Elna Cerafine for the 16 + 16 uF capacitor and DNM solid core speaker cable for internal wiring - will send in photo' when units are finished. If you are contemplating restoring a pair of Quad II amps, PLEASE do not attempt to drill the chassis to fit modern power supply leads and phono sockets. Quad can supply the necessary adapter leads so you can use modern pre-amps and independent power supp ies for the Quad's using the original connectors; please e-mail me if you require further information on this. I'd be interested to hear from anyone out there who is/has restored these classic amps, and any hints, tips or pictures would be greatly appreciated! Cheerio!

Comments:
Great site. WANTED: FM3 or FM4 tuner to match my other gear. Will travel to collect.

Comments:
I have the above items for sale. The FM3 and amp have just been serviced by Quad, they looked at the control unit and passed it as OK. Offers?

Comments:
I have had my 44 pre-amplifier for about 10 years now. But ever since new the input keeps either reselecting the tuner input or not selecting anything at all. Sometimes you cannot select any input at all even if the unit is switched off then on again! Qua have repaired it 3 times it still does it, can anyone help with either an alternative circuit or update? I do not recognise the logic chips used in the selector circuit and cannot find them listed anywhere.

Comments:
Great site. Everyone who is fond of Quad must support it and, if they can contribute with information. I'll send some documents I have about the 33 and 303 soon.

Comments:
Is there anyone who remembers Mr.F.B.Griffin of Griffin Radio Ltd., in Bristol Street, Birmingham? I was involved, as an employee of the company, in introducing concept of hi-fi and stereo to the public during the birth of twin channel sound on disc and t pe when it was first developed. My company organised demonstrations in Birmingham Town Hall and West Bromwich using Quad system and demonstrating live versus recorded sounds. We also formed and ran music club in the basement where we used the finest equipment to introduce our patron to lassical music. And those who knew, came to hear their favourite music played on the system which gave 'closest approach to the original sound'. Nostalgia prevails and Quad has moved on since those days of the Kinkless Tetrode, KT66 and the Pentode, EL34. I would love to hear from my lost but unforgotten colleagues who were patrons and customers of Griffin Radio in 1960's and 70's.

Comments:
a really exiting information-night and photos which keep history alive!

Comments:
I would like to thank the person that created this valuable reaserch.

Comments:
Hi! Me again. I would love to have a cooling finned beauty(303) on each side of the 33,FM3 *lush looking* Now how do you bi-amp, and what good would it do??? (apart from visualy) THAAANKS

Comments:
Hi again! i am wondering if i should continue using the old DIN-connectors that came with the gear when i bought it ? seems a bit strange to use a nordost interc. and plug it into a 20yr old lead?? Can anyone give me an idea of how much a pair of old but orking(ish) 57's are likely to cost? I want them even though i've never seen them irl(not to mention listend to them)My old, phillips cd692, is breaking up. Any ideas what would suit my lovely quads???(i'm not rich)THANKS Magnus from Bristol UK

Comments:
The Quad 405 circuitry was changed (to mark 2 status)to allow the amp to better handle very low impedence loads. In the mid 70's Quad arranged some blind tests of the Quad II v Quad 303 v Quad 405 - the results of which indicated that guesswork was as goo as anything in determining which amp was running. In other words, they all sounded the same.

Comments:
Can anyone tell me what the difference is between a 405 and a 405-2. Also is it true that the 405-2 produces the sound that most resembles a tube (valve) amplifier (ie the QUAD II)?

Comments:
Great site. Today I bought a 'NOS' Quad 77 integrated. A local Dutch dealer sold about 10 boxes of em for HFL 999,- each! (approx. 250 Pound. As of today they still had some left. The shop is called RAF and is based in Amsterdam). Only thing missing is the remote control, but I wonder if I could mimmick the commands using the infrared features of my PalmPilot, which can be programmed. Any suggestion welcome!

Comments:
The understated styling and superior sound of this wonderful equipment has fascinated me from a young age. I'm lucky enough to own a mint condition set up but am looking to buy a second 405 to run the pair in mono, I understand that quad do a lead, but d the amps need to adjusted or fine tuned in any way to equalise output? Great site, best wishes Ian Holden

Hi, thanks for a great site. I bought my quads two weeks ago and Yes i love the sound compared to the modern stuff i had (backgrade is better than upgrade:-) But i'm getting the itch, i would like to buy a pair of ESL-57's to complement/replace my B&W 601 2's (even though i've only seen them on the web so far, but who cares ?) I live in Bristol, e-mail me :-)

Comments:
quad 77 series had short life does any owner have any strong views about its performance good or bad. I was hoping to upgrade to it later on but the newer 99 series is out of reach. Now the 77 series rarely appears in the hifi press. how provacative might the view be that the 99 series is the 77 in a new box?

Comments:
great site; I would like to buy 77pre/707, cosmetic condition unimportant, sonic condition v important. Also, I think the ESL's could do with a recondition. Any suggestions where to send them? Is Quad themselves the best? Anyone else do good work on hem? I'm located just south of London. Thanks

Comments:
I love my Quad, but would like to bring it up to a modern spec, rather than replace it. I've seen the suggestion in the guest book about replacing the pot and the electolytics. Any other suggestions regarding component or circuit changes? Anybody changed the DIN sockets for phono? Should I chuck the 33 away, and use a different preamp?

Comments:
Is there any specilist have the circuit diagram of Quad FM1 and AM recevier diagram?? Please inform me if you have the circuit diagram. Thanks a lot!!

Comments:
The folk at Quad in the UK are really good at replying to email - contrary to the comments on this site. I also spoke to them and assured them that I would send you this favorable comment. Ian Montgomery

Reviving it after almost 10 in the box. Running ito problems, one channel working, balance control flat, etc. Any tips, pictures, diags, mods, etc would go a long way. Great site and good to learn of the large Quad family!

Friend just acquired an original AM tuner (ie not AMII), with QCII control unit and single Quad II amplifier. Control unit lights up "Acoustical" (ie not "Quad". Any thoughts on age of these items? Quad II is serial no in the 5000 range. rg

Comments:
I have a couple of interesting pieces - a 2 chassis power amp that appears to be a forerunner of the Quad II. On the amp unit there is a gold colored nameplate which reads "A GENUINE DTN WILLIAMSON AMPLIFIER made in england for bitish radio electronics lt . no. 1 thomas circle washington, 5, dc". It has a pair of KT66, 2- 6SN7GT, a pair of large rectangular metal can caps and a huge output transformer. The power supply unit is on the same size chassis with a power transformer same in size as the output xformer, a large and a small choke, 3 large rectangular metal can caps, and a 5V4G rectifier. Each cassis is eqivalent in size to a QUAD II and is painted in the same grey finish. SER # on p.s. unit is 190. The matching preamp is a "QUAD CONTROL UNIT" type QCII. There is also a tuner "QUAD" with MW/SW1/ SW2. I would appreciate corresponding with anyone who might have info on this amp and p ssibly picking up a second piece.

Hey, all Quad fans, I need some help for finding a suitable pickup for my Quad equipment. I know DECCA made the best cartridges in the world, but here in North America they are soooo expensive!!! I checked http://www.warrengregoire.com/hifi-stereo-phono artridges.htm, and found even the suckiest DECCA, at least better than those low output ortofon or clearaudio carts, costs $550. Oh man, how can I afford this luxury? I also attempted to bid for a vintage DECCA Deram cart in ebay, and found it is a 50mv type which does not fit my Quad 22 with type A adaptor. If any British Quad fans know where I could find some cheap and brand new carts in Britain, tell me. Also, tell me if you know a superior replacement for the DECCA carts. Many thanks to all.

What a fab site.Futher improvements for the 33pre,change the original vol pot to a "Blue Alps 50k dual log and fit a remote mains switch.Upgrade the smoothing caps in the power amps these can be obtained from either maplins or RS.Personally id go for RS a they have a better selection and are cheaper.Changing the caps in the 303 with new cap reaps a huge sonic difference

Comments:
Most of you will realise the horrific "thump" of the 50E when it's powered on. I find that a polyester capacitor of 0.1uf 400V soldered parallel after the output from the transformer (which outputs at 38V) and before the diamond rectifier configuration wi l help minimise noise and reduce the "kick" to a very tolerant level. The 400V level was chosen after taken into consideration the split second spike when powered on in which might reach to about 300V. Comments anyone...?

Hi, this is my second visit. I have just come upon an AM III tuner, with valves, looks to be similar to the AM2 discussed on this website, but in a more modern square case.

Quad II Power and preamp needed for a re-build of Paul McCartney's original "coffin" bass amp. I built the original one for Paul in Liverpool before there were any high powered bass amps available. It was lost around the time they came over to the states. This will be as close to the original as I can make it, and will be presented to Paul himself upon completion. Please contact Adrian Barber if you have any leads at adrianbarber@hotmail.com or my tech, Sam Newcomb at zenode@earthlink.net Cheers Adrian

Dear Sir, I’ve apologize for my English and I’ve give you a great regret for helping me to make copy of amplifier device “QUAD 405-2”. I had a great help from information, which Mr. Ludwig had given me to improve device. Model “QUAD 405-2” has some elements, which parameters are not familiar to me, such: What is voltage parameter for zener diodes D8 and D9 and what does firm produce them? (How do they mark them?) Does inductance L4 have parameter of 22?H or 2.2  549;H? Does it wind up in the air or on the ferrite? What are dimensions of ferrite body (diameter and length)? What are dimensions of the wire for wind up (diameter and length)? Does you have better circuit diagram of “QUAD 405-2”? If you haven’t this information, please tell me where can I find it? Does you have new e-mail of Mr. Ludwig? I will be very grateful for all your help. Sincerely yours, Mr. Crnogorac

Great site! I have been a Quad nut for over 30 years when as a student Electrical Engineer I bought a pair of used ESL57's and made the 33/405 copies mid seventies. The ESL63's came in 1982, the 77 units in 1998 and everything still sounds fantastic. My n xt project is to compare my superb (sealed box, active crossover) subwoofers with one of dipole design.

A site like yours is long overdue - personally I hope that you will in time consider including all of Quad's products, as they are always innovative, eg current dumping amplifers (405) and interactive remote controls (77 series). Try to get as much techni al information that you can, circuit diagrams and infomation, what to look for when buying, etc. This would be very useful. When you buy Quad gear you definitely feel part of a family - more so than with just about any other. WWell done. Kind Regards Keith

I assure you that the sound is quite a step up from the 405/2 & 34 I owned before this. I have been wit QUAD since I was 16; so I'm celebrating my 20th this year. Thanks QUAD WORLD for making it possible for QUADOPHILES to be in contact.

What a wonderful site - I was looking for info on Leak TL10's when I found it. I have nearly completed restoration of my amps following Russ Andrew's old guide, which I found very useful and I was most interested to see your own similar restoration work. hank you for the details of equivalent valves.

Quad is fantastic. I bought the 77 series because I thought that it had more 'life' than the 67 which I was originally gonna buy but still the same great qualities that Quad have been made famous for. I look forward to seeing other Hi Fi speakers come and go whilst I still sit and listen to the ESL-63

Excuse me for my bad english. Please, help me!!! I am from Bulgaria and I work in computer firm. My hobby is building and listening to amplifiers. Now I want to build a QUAD 405-2 amplifier, but don't know how to make the inductances L4 (22mkH) and L2 (3 kH). If anybody has the original dimensions, wire thickness, diameter of the coil and number of the turns please send me!!! Thank you!

A guy traded me a set of 405 and 44 yesterday. I just put them into my stereo system in my living room with my B&W P5 speakers. Great sound for '70's jazz music! I found there are some magic knobs on the 44 pre... can anybody scan the owner's manual of 44 pre for me? (or for everybody in Quad World?) Thanks!

Comments:
I picked up a cheap Quad33 pre, sorry control unit. It's nice, but at low outputs the volumes control is a bit 'digital' on the left channel, ie. quiet, then suddenly quite loud. I've cleaned it out with switch cleaner, but still no joy. Any cheap way to change the volume control, bearing in mind the attached power-on switch, and the relative cheapness of 33s.

Comments:
I'm trying different Quad-combinations, and suprprisingly I seem to prefer the 34 as preamp with the 606-2. The 34 is not very transparent, but in terms of musicality and enjoyability it beats the 66 Pre. And the tone controls are extremely useful. Thanks again for a nice site! I'm looking forward to information about the newer Quads.

I have just bought QUAD606 2 weeks ago ! Very nice sound ! But i have to improve my installation by changing my old preamplifier (amadeus). Anybody could you advise me ;if it's better to buy the QUAD 66 preamp rather anything else. Best regards Jean from PARIS

I bought my first 57's in 1962. Right now I am experimenting with stacking a pair of 57's above a pair of 63's! I hope to capture the best qualities of both! One of my pairs of 57's have burnt treble panels (arcing). I want to follow Sheldon Stoke's i structions to rebuild them. Please send me an e-mail with your stories .

Comments:
My 405 Amp has given me nearly 20 years of good service, but recently one the power transistor blew, so I replaced all the tranistors but now about 10 minutes turning it on there is a loud pip from one channel then it goes dead. I have the swapped the boa ds over but it still happens on the output from the same board (so the problem must be that board). Does anyone have any ideas what could be causing this. (What other components should I replace?)

Comments:
Does anyone out there know of any esl 57 diaphram coatings other than graphite? I ve got 13 panels to rebuild and a easier method of coating them would be gratefully received. Just a note to say that if you love the sound of the esl 57s, try them stacked, they lose nothing of the original, wonderful sound quality, and gain loads in maximum volume, bass extention and lack of dispersion. They then sound better than the esl 63s in all respects apart from imaging. great site, i`ll be visiting again.

Comments:
I was inspired by the site and decided to take my Quads out from mothballs... I still have the original polystyrene cases and shipping boxes with all labels intact! I had them since the early 80's and plan to resurrect them so that they can take their rig tful place in my living room... QUAD Rulez!

Comments:
Oops! That should have been 'There ARE a couple', not 'There IS a couple of articles' sorry but that was irritating me! Also I noticed that Maplins (UK chain, but they also have a web site) sell 4 pin DIN plugs, which could be useful for anyone wanting to roll their own connects between say a Quad 33 and a poweramp with phono inputs.

Comments:
Great work! Does anybody know where to find exhaustive documentation on pre 34 and final 606? I don't have it any more. If you want to share with me your HiFi ideas, don't worry and mail me!

I'm currently trying to find out why in my set-up I'm not having the "depth" I would like. IOW definition of the instruments from left to right on the imaginery stage is OK, however, they seem to come all from the same plane between the two speakers, henc no (or very littel) depth. I've been told this most likely due to the 34 pre-amp. Any comments ?

Love this site! To 303 owners: Does anyone know what transistors I can use to replace U17219, U17229, and 16012 with? These old fossils don't seem to be in any cross reference book here in Canada. All the others seem to be listed. I have received the tip of exchanging th old power transistors (2N3055) with MJ21194 and then carefully rebiasing the amp so as not to burn it up. I'll certainly try it out. Anyone else tried this?

I have made some mods to my 405-2 (power supply and t-network capacitors from DNM, cabled with kimber cable) Magic sound!!! However the two power output transistors 17556 keep over heating and blowing on one side only. The amp pops on power-on, (in-curre t too high) I can't track the fault.... any ideas??

Comments:
Filter and bass-lift knobs on my 44-preamp are scratchy and sometimes even mutes one channel. There is also a silent hum on the left channel. Is this caused by oxide on the controls? If so: how should I clean them? Is the hum caused by inadequate earth due to oxidation somewhere? Thanks, Hans Ramo Stockholm, Sweden

Comments:
Thank you for spending time setting up this Website. The contacts and hints list were very helpful. I would also advise a RATA (Russ Andrews Turntable Accessories) upgrade.

Comments:
Does anyone have any info on modifying the 33 or the 303? How about adjusting it? Any help or suggestions are desperately needed as... our power amp is broken. The schematic diagram on this website is so diffuse that I can't make out what the part designations are, so it is very difficult to replace old unreadable parts. I love the great mod suggestions for the 405!!!!

Can anyone out there tell me how to stop or minimise the THUMP! when I switch on the Quad 50Es...? I ran through the circuit diagram of the 303 power amp and I saw that there was a ceramic capacitor (no.C4 in the diagram) value : 0.03uf 250V while the 50E doesn't. Can this be used in the 50E..? Please help...I don't wish to blow my speakers..

At one time I owned all of the above mentioned gear, sadly I had to sell off all except the 63s. I miss the midrange of the original 57s but am happy with the overall performance of the 63s I live in West Australia where Quads are too expensive and rare as I believe there is no dealership that caters to Quad equipment here.Pitty as the equipment is second to none.

Comments:
Thank you for a great site! I especially appreciated the interesting Quad 405 modification document by Bernd Ludwig. I am going to try these mods on my old 405 (# ca. 19000). Many thanks to him too! I'm really looking forward to the documents about the 33/303.

Great web-page! I just adquire my first pair of vintage 33/303S, so I thougt I should sign up here and be welcome to the club. Looking forward to see the 33/303 info on line! By the way, my unit is 303S, not 303, why, is there any difference with the one amed just 303? Something else, has someone try to upgrade the 33/303 by placing new caps, better resistors, etc? I'm feeling tempted of doing that -engineer as profession, how can I be quiet when I have such a lovely piece of engineering in front of me!-. Do you think is worth the effort or it's better to wait till things break down? Finally, how can I get schematics from the 33 unit? I would appreciate it if someone could send me or fax me a copy. Cheers!

Hi: I have a Quad II amp and a Quad control unit QC II and am interested in selling these pieces. I would like to know the value of the units and if there are any interested parties. Thank you.

Comments:
I have a pair of Quad II's which sound great through my Lowther Speakers. However one of these develops a slight ticking sound after being on for a few hours although not that loud it is in very irritating (Chinese water torture type stylee), and I was wo dering if anyone else has found this problem? I've changed the Valves over, and had most of the internal resistors and small capacitors changed. Great site again! Incidentally I compared a Quad 34 and a QCII pre's through the Quad II's and although there asn't much in it, the QCII did have the slight edge in sound quality, if not noise. Progress Huh?

I aquired a set of 3 series equipment some months ago, including a rare, coffee-table type cabinet, made either by, or for Quad, which includes space for the control unit, an FM3, and under a removable panel, the 33 amp.

Great site!Both looks great and is intresting to read. Looking forward to read about 33/303/FM3 which I have had for over 10 years. Some electrolytics has passed by during the years, one rather loudly, but I like my gear.

Great site! Lots of info. on vintage QUAD gears... it would be better if more info. on recent vintage QUAD gears like 606 Mk I, 34, FM-4, ESL-63, (or even) 77-series... etc. are included in this site. I like my QUAD gears. I have some other gears as well but whenever I go back to my QUADs, I never want to get rid of them: I never get tired from my QUAD gears. They really make music! A lot of people here talk about QUAD 303 power amp... when I first acquired my 303, I was surprised that it could drive my ESL-63 with satisfaction results! I got mine, with 33, for $285 Canadian dollars (~180 US) so it is cheap. I have a couple of Decca/ ondon recordings on CD which said that the recording engineers used 303 as the monitor amp. so I have a piece of recording engineering history to boot. Mine is modified with a pair of RCA phono female plugs such that I don't have to use the DIN cable when I couple it with, say, QUAD 34. Talking about 303, a few visitors of this site said that they have the monoblock 303s... it that true? Did QUAD really make 303s in monoblock configuration?

I have been trying to modify my pair of QUAD II. I believe that the original circuit is designed for driving the low efficient speaker, namely ESL, and not perfect match for high efficient speaker such as Tannoy monitor. I recently found a good circuit schemantic from LEAK home page about the phase splitter. I just remove EF86 and replaced with a 12AUX7, dual triode with LEAK circuit. I get so much more music from my system. I use russian tubes and Tannoy monitor. Only ne thins is I get very tiny gain, probably 4W output. It get enough volume without a input volume control. I will let you know more if you are interested in my modification.

Comments:
To JWHM question: By running the Quad II on the wrong voltage setting means that the high tention (and low tention for that matter) voltages are greater, 360ish i.e. instead of 330 Volts, this extra drive inside the valve gives a little more 'oomph' but w ll shorten valve life, and probably wont do the long life running of the amp any favours. But hey it's yours, and enjoyment you get from it is that's important. It may not be needed if you change you speakers to something more sensitive. By the way check f the output transformer set to the correct speaker impedance? By the way does anyone know if Quad produced a Long Wave tuner in the 33 series? A LW3? Does anyone have one? Maybe they would want to sell one?

Comments:
Great site, very usefull and unique information. I'm currently looking for a second 405 Mk I and information for bi-amping with 2 * 405 Mk I Amps. Also a pair of Quad II would be nice ... My current Quad set-up is complete with the Rega Planet CD-player, a TEAC tape-deck, monster cable interconnects and Misson 751 bi-wired with misson bi-wireing cable. Great sound, hope it will be even better if I can bi-amp 2 405 Mk I amps. Keep up this good side.

Hello, dear Quad fans, A site like this is really a surprise !!! I am using my Quad II + Audio Research LS7 as pre-amplifier, the Quad 22 sounds sweet but not airy, may have something wrong with it. Dear fans, would you please advise me the following -- 1. What small monitor (wall-mount type, could be posited close to a rear wall) with high sensativity is best suit to the Quad II??? 2. I find that the "voltage adjuster" was best set on 210- 229 to produce good music with texture and strength. However, the place I am living has a voltage of about 250 (Australia). How come??? If I set it to 230-250, the music becomes slow and unpleasan . Do you know why??? (speaker using 88db, recommand 15-60W) Thanks. ps. setting to 210-229 is a real "up-grade"?

Comments:
I have a resonable pile of spares for most of the valve stuff and can supply reprints of the Quad 22/11 owners instruction manuals. I also make the adaptor pods for the back of the Quad 11 and 22 Control Units, including one for CD which plugs into the ta e adaptor socket. I can also advise on how to replace the original rectangular capacitor in the Quad II amp with new caps which fit inside the original package (without destroying the cosmetics of the original!!).

Comments:
I am interested in how people have got over the phono input 'problems' of the old cans on the control unit Also recommended speakers, I currently use Heybrook HB111's which are pretty good for the money but I'm interested in upgrading. Is the QAD67 a good CD match for old QAD valve stuff ? Finally, any recommendations on different pre-amps for the valve power amps. I'm interested on upgrading. Anybody into old QAD gear (or old radio stuff in general) gear MUST visit Watts Radio in Somerton, Somerset, England and speak to Jim - a really fascinating engineer and character.

Does anybody wants to know how to "upgrade" a 33 preamp using the 44 Aux Input and Tape modules in place of 33 tape adaptor, in order to improve its performance, altering only a little? Just ask me! I did it with mine and it sounds pretty well with CD pla er and FM. By the way, very nice homepage. The best place for Quad lovers and enthusiasts.

I don't think many people (including Quad-ites) know about the Quad 50Es. They are supposed to be used in mono per block but I've acquired a pair and now being driven by the 33 pre-amp. They sound much more detailed and have a lovely soundstage, but they on't have as much "pow..!" as the 303. Heard a whisper that they were used mainly for studio work. My system : Sony CDP338-ESD, Quad 33/303/50Es, Epos ES-11s and Oerhlbackabel for speakers and computer shielded networking cables for all interconnects...! ail me for more stories...!

Comments:
I am an audio enthusiast (Engineer) with substantial r&d experiance - and much enjoy the easy warm sound of thee full Quad system, have rebuilt ALL of the units to an exacting standard using essentially the same valves as is, I was fortunate to purchase a uantity from the MO valve comany prior to them stopping production in the late 70.s early 80's. The system is good fun and perform VERY well for the vintage, but well engineered equipment using high grade currently available devices can, I am afraid out p rform, the best restored units - yes my units use the same level of component quality, however they are capable of quite outstanding performance, especially when the 57's are stacked to improve the bass presence - yes I could live with them. - PLEASE PLEA E maintain the current works - I had no end of problems sourcing an AM manual.

I have huge stock in hand, US$40 each or US$35 for 10 tubes or more. Do not mistake these with the Telefunken EF86 that Angela is selling. These are the best EF86s you can ever find. If you are keen, send email to yctan@edb.gov.sg.

I got the answer to the adapter card mods in order for a 20 Year old Preamp to take a CD input!!!. I am but only impressed. Thanks go out to the UK Quad Service Dept for the info. If anybody else needs this or wants it, I can scan and mail for you.

I recently bought my equipment and I would like to know if there are any modifications I should do to improve them even further? Like changing the connectors. Any ideas? Should I leave them as original as possible?

I've had my Quad from new in 1974 so it's pretty long in the tooth, and has seen me through several upgrades of other components. Assuming that at some point it gives up the ghost, what would I need to buy (Quad or otherwise) for comparable quality, and h w much should I budget. Really, just how well does 25 year old hi-fi stand up to more recent designs in terms of sound quality, value for money, etc? Anyone out there in cyberspace got any ideas? I listen to a wide range of music - classical, rock, fol (but mostly Grateful Dead!!)

Enjoyed looking at the pages. I've enjoyed refurbishing my own Quad stuff - including getting a Quad FM tuner back into tip-top condition, aligning it precisely according to the Quad instructions. If you were to make available the alignment instructions for the AM2 tuner, then I woul line that up by the book, rather than just how I guess it should be aligned. I remember first seeing Quad stuff in the 1950's when I was a kid, so having the complete set-up now provides an example of, as Sigmund Freud said, the only true source of happiness - the fulfilment of a childhood wish. Cheers, martin

I have recently purchased a Quad 33 and 2 x 303 units. I am runnng the 303's seperately for left and right channels. I have taken a look at the cct diagrams and feel it would be quite simple to change the disk adapter board to accept CD input. I do not require any form of cartridge pickup input and am willing to sacrifice any options I thought might have been included for one of the edges on the disk adapter board. Can you give me the info required to achieve this or put me in touch with someone who has done this.

Comments:
Great site! I am looking for a quad pre-amp to mate with the 303.

Comments:
I'll get back to this page later on when I can get all the info on my Quad system. Quite glad to have found this web site.

In answer to the people after interconnects. I had a two Phono to Quad 4 pin (303 power) Chord Crysallis. These can be made up by the Chord company for a little more than the standard versions. (I have no connection, financial or otherwise).Although I had nothing else for a straight comparison it seemed fine. I believe this type is known for it’s bright sound which combined with the “Laid back” sound of the 303 (and most other Quad transistor amps come to that) it worked quite well. Again great site, Keep up the good work! Hans Overgaag, read the 22/II article in the Info section, watch out for your power transformers! Some words from my sponsor! My 306 is still for sale, for 180 Pounds Stirling, Come-on Get em while they’re hot! etc. etc.

Comments:
I have never liked the 57's on the floor so I have experimented by taking off the legs and putting them on Target HJ15/3 stands. For those of you who do not know this stand it is 15inches high and has a massive top plate being about 11inches by 11inches. The speakers sit very nicely at the "correct" height.I wonder if anyone else has also tried this.? By the way I use Chord Rumour speaker cable and I wonder what you all recommend. tim

Hmm.. nice site! Personally I can’t wait to you get to the more modern (i.e. only 30 year old) stuff. I just love the design of the 303 It’s the cooling fins on the back that gets me everytime! I always found these a bit strange as my 303’s never ran warm at all, still, lots of photos of the fins please!

I think I am addicted! Looking for 2 more ESL57's. Help me Quads Anonymus!!

Amazing! I never thought Quad lovers were crazy enough to this extent(myself included). Anyway, I have been a Quad lover for a while and delighted to know there is a forum where likeminded people can exchange information and help each other. If anyone is nterested, I am willing to share the Quad experiance. Equipment owned: the pre/power combo is connected to Maggies,Marantz CD 63SE, Musical FIdelity X-10D, Cable Talk Monitor 2 interconnect, Studio Power Line Speaker Cables, and last but not least Rega Pl ner 3 Turntable with RB 300 Arm and Ortofon cartridge.

Comments:
Nice Site!! I've been a Quad user since 1970 and I still think it's great stuff.

Comments:
Arc! Arc! That's the sound of the trained Seal of Approval making admiring noises (much like a treble unit) for your site. Imagine the Seal flapping its fins in delight as it sits in the sweet spot, leafing through some of the most elegant Web pages in hifidom. Great work! I'm a former Quad dealer in San Francisco who's now out of that business, but am putting together a classic system with the help of one Sandy Baccaro here, otherwise in the US known as "Dr. Quad." I'm off now to pick up a cherry-quality 22 preamp for $90 US. It think it's a fair deal, considering it's from the original owner and carries all documentation. I'm excited! Also awaiting my ESLs 57s from the boys in Virginia that contain the (drum roll) much-anticipated German treble units. I have my fingers crossed. They'll be hooked up to my Quad IIs (replacing a Bedini 25/25 I used to use on a pair of stacked ESL 57s) and I'm set. Still searching for FM and AM tuners, and a mono preamp (11?) just to complete the kit. Again, congratulations on a beautiful, well-written, well-wrought site.

Hi folks, I'm looking for some help by rebuilding my old lovely ESL57. Do you've got some links to documentations or do ya know a place to get replacement stuff?!? Send me a short mail to sunny switzerland! Cheers Joe.

Comments:
Someone posed a question a while back about interconnects. Does anyone have any idea as to the likely sound improvement to be achieved by replacing the interconnect between th 33 pre-amp and 303 power amp. I'm still using the flimsy lead supplied when I bought the amp nearly 25 years ago!! Also, let's not forget what the hardware is for - MUSIC!! Mine gets used mostly for listening to Grateful Dead and associated music. If you've never heard them, check out some of their live recordings.

Sooner or later I'll find a Quad II! Great site, my best wishes Mimmo Cacciapaglia TNT-Audio Internet HiFi Magazine

Comments:
It kinda' restores my faith in the human race to see so many nice comments about some great hi-fi gear. I am a former owner of II's, 22, FM1, FM3,33, 405, and ESL's. Nowadays I jam to a remarkably compatible power amp/electrostatic combo, Atma-Sphere M -1's upgraded to MKII status and Martin-Logan re-Quests, hosed together with Monster 1.2 (bi-wired). Everything I read says this won't work. Don't believe it! Anyway, congratulations on a terrific site. I'll be back.

Comments:
Can anyone help me with a suggestion as to what high end interconnect cable to use between the Cd player and the 33 preamp, and if possible what speaker cables. Thank chaps. This is a great site !

Comments:
Hi all, I've had some problems with my email over the last week (20-29th May), so if you've written, and not heard anything back, please send again - many apologies...

Comments:
Nice site. Hope soon site will contain info on rebuliding a quad 405. Bernd Ludwig sent me a upgrade cookbook on the quad 405 (thank you). I need some schematics (Circuits ??) on the amplifier. Can anyone help me?

Comments:
Compliments for your site. I changed the KT 66's, to save them, for Mullard EL37's. These have the same quality sound as the GEC's. My experience with modern valves, whether Sovtek or Chinese, is that these all sound inferior. Keep up the good work to maintain this site at this level.

Any QUAD fans have the following parts? QUAD II's red and black speaker connections and a voltage selector plate (with selector). I desperately need them because they are broken. I would pay good price for these parts. - Byron Chiang

Great site - waiting with baited breath for info on the 303's and 405's. I'm going to be over in London in a months time so does anyone have any ideas where I can locate some Quad 44 Pre-amps. There are two others who also have 405-2's who are looking for pre's as there is not much in the 2nd hand market down-under in New Zealand.

Comments:
The only gears that haven't been replaced by me in the past 6 years. It will certainly last for another 6 years of listening.

Comments:
great site i hope it really goes well

Wanted QUAD II and 22 manuals. Would accept photocopies, but original manuals are preferred.

Comments:
Great site!.. I'm looking for more information about the 33/303 combo (manuals, schematics...) and modifications. Thanks

Comments:
The 405 is still a marvel - the main problem is the poor input-stage (+23dB for a single veteran OP with poor ps-decoupling!). I did some simple upgrading with good success and am interested in other´s experience.

Comments:
I have an FM1 for which I need an external stereo decoder. Bizarrely, the tuner's  330v supply is returned to the QUAD 22 via the screen of the phono lead. I presume this will fry any decoder not intended for use with the FM1. QUAD's own decoder is genera ly accepted to be rubbish so, anyone know the solution? Any advice gratefully received...

Comments:
I use my system everyday and it's far more dependable than my car ! I have replaced always been able to replace components when needed (405 power capacitors, 606 power transistors (oops a little accident when evaluating speaker cables) One coment: I replaced the internal wires from the phono inputs to the boards on my 606. Although now a convert to the merits of speaker cables and interconnects (previously a cynic) Im constantly amazed how even a 6 inch bit of wire is really a component. I think i ot considerable improvement.

Comments:
I am very pleased to note there are some people like your goodselves have done somethings to keep and maintain those vintage gears last for the younger people to learn or own.

Comments:
What a pleasure !!! i am 37. i have my quad system since i was 16 ! My quad are totally reconditionned.

Great site. Has anyone tried the McGowan 63 mods?

Nice to see another site pop up which continues to promote some of the best vintage equipment available. I'm surprised you dont have a pair of 57's. If anyone wants any repair work to 57's let me know. I am UK resident.

Comments:
Very nice site with beautiful photos and comments.It would be very nice if you could give information about the "Limited edition of QUAD II" comparing to the previous " QUAD II" on your website .

Comments:
I love Quad and am looking for more Quad II and FM2 with stereo decoder. The Quads sound a little stressful with the Spender LS3/5A that I have. That is the reason why I am going to get one more pair and driving the bi-wired LS3/5A in bi-amp mode. Also if anyone out there know where can I source female power plug for the Quad II and 22, pls let me know. I desparately need that.

Comments:
Very nice site. I liked the organization and am looking forward to your additions. I am a Lux tube fan myself, but I enjoy ANY old Hi-Fi gear. I have heard the ESL's and the ESL63's and found them to be excellent. I would consider purchasing a pair of ESL's if the right ones came along.

Comments:
The ESL is a very special audio component that relatively few people in the world can appreciate. It´s the best speaker in the world. I prefer it with tubes,(old tube amps better). My hobby now is to find amps for them. I apreciate experiences with them, please E-mail.

Hi Ade! Very nice site..

Comments:
Can anyone out there help?! I use a pair of ESL63 from years ago, after using before them, the MARK 1 speakers from QUAD too (more than 10 years !). I asked the factory why there is a 220 microF//1.5 ohm cell on the hot wire of the FRED and what would happen to the speaker (or the amp) if that cell is removed. I never get any answer... Can anyone help me - please feel free to email me...

Thank you very much for your page. Very informative and artistic. We all share the same love for this wonderful and ageless equipment. -Thank you

Quad gear you own: Stacked ESLs & a 303

Comments:
The Quad ESLs have been a standard for many years and continue to hold their own. Amazing! The 303 is a great small amp for monitoring purposes and of course sounds great with the ESLs. It is built like a tank for 2x35!

Can't wait for more info...
